NAME

smcron - manage jobs in the crontab database

SYNOPSIS

/usr/sadm/bin/smcron subcommand [ auth_args ] -- [ subcommand_args ]

DESCRIPTION

The smcron command manages jobs in the crontab(1) database. subcommands smcron subcommands are: add Adds a job to the crontab(1) database. To add a job, the administrator must have the solaris.jobs.user authorization. To add a job to another user's crontab file, the administrator must have the solaris.jobs.admin authorization. delete Deletes a job from the crontab(1) database. To delete a job, the administrator must have the solaris.jobs.user authorization. To delete a job from another user's crontab file, the administrator must have the solaris.jobs.admin authorization. list Lists one or more jobs in the crontab(1) database. To list all jobs, the administrator must have the solaris.jobs.user authorization. To list a job in another user's crontab file, the administrator must have the solaris.jobs.admin authorization. No authori- zation is needed to list a user's own jobs. modify Modifies a job in the crontab(1) database. To modify a job, the administrator must have the solaris.jobs.user authorization. To modify a job in another user's cron- tab file, the administrator must have the solaris.jobs.admin authorization.

OPTIONS

The smcron authentication arguments, auth_args, are derived from the smc(1M) arg set and are the same regardless of which subcommand you use. The smcron command requires the Solaris Management Console to be initialized for the command to succeed (see smc(1M)). After rebooting the Solaris Management Console server, the first Solaris Management Con- sole connection might time out, so you might need to retry the command. The subcommand-specific options, subcommand_args, must come after the auth_args and must be separated from them by the SunOS 5.8 Last change: 5 Jan 2001 1 Maintenance Commands smcron(1M) -- option. auth_args The valid auth_args are -D, -H, -l, -p, -r, and -u; they are all optional. If no auth_args are specified, certain defaults will be assumed and the user may be prompted for additional information, such as a password for authentica- tion purposes. These letter options can also be specified by their equivalent option words preceded by a double dash. For example, you can use either -D or --domain with the domain argument. -D | --domain domain Specifies the default domain that you want to manage. smcron accepts only file for this option. file is also the default value. The file default domain means that changes are local to the server. Toolboxes can change the domain on a tool-by-tool basis; this option specifies the domain for all other tools. -H | --hostname host_name:port Specifies the host_name and port to which you want to connect. If you do not specify a port, the system con- nects to the default port, 898. If you do not specify host_name:port, the Solaris Management Console con- nects to the local host on port 898. You may still have to choose a toolbox to load into the console. To override this behavior, use the smc(1M) -B option, or set your console preferences to load a "home toolbox" by default. -l | --rolepassword role_password Specifies the password for the role_name. If you specify a role_name but do not specify a role_password, the system prompts you to supply a role_password. Passwords specified on the command line can be seen by any user on the system, hence this option is considered insecure. -p | --password password Specifies the password for the user_name. If you do not specify a password, the system prompts you for one. Passwords specified on the command line can be seen by any user on the system, hence this option is considered insecure. -r | --rolename role_name Specifies a role name for authentication. If you do not specify this option, no role is assumed. SunOS 5.8 Last change: 5 Jan 2001 2 Maintenance Commands smcron(1M) -u | --username user_name Specifies the user name for authentication. If you do not specify this option, the user identity running the console process is assumed. -- This option is required and must always follow the preceding options. If you do not enter the preceding options, you must still enter the -- option. subcommand_args Note: Descriptions and other arg options that contain white spaces must be enclosed in double quotes. o For subcommand add: -c command Specifies the command that you want to run. -h (Optional) Displays the command's usage state- ment. -m day_of_month (Optional) Specifies the day of the month you want to run the job. Valid values are 1-31. If you specify both -t and -m options, the job exe- cutes one day per month at the time specified by -t. -M month (Optional) Specifies the month that you want to run the job. Valid values are 1-12. If you specify both -t and -M options, the job executes during the specified month at the time specified by -t. -n name Specifies the unique name of the job. -o owner (Optional) Specifies the user name that is the owner of the job. If you do not specify this option, the user name specified by the -U option is assumed. -t time_of_day Specifies the time (in hh:mm) that you want to execute the command. If no other time-related options are specified (-m, -M, or -w), the job executes every day at the time specified by -t. If you specify both -t and -w options, the job executes one day per week at the time specified by -t. If you specify both -t and -m options, SunOS 5.8 Last change: 5 Jan 2001 3 Maintenance Commands smcron(1M) the job executes one day per month at the time specified by -t. If you specify both -t and -M options, the job executes each day during the specified month at the time specified by -t. -w day_of_week (Optional) Specifies the day of the week you want to execute the command. Valid values are as follows: o 0=Sunday o 1=Monday o 2=Tuesday o 3=Wednesday o 4=Thursday o 5=Friday o 6=Saturday If you specify both -t and -w options, the job executes one day per week at the time specified by -t. o For subcommand delete: -h (Optional) Displays the command's usage state- ment. -n name Specifies the unique name of the job. -o owner (Optional) Specifies the user name that is the owner of the job. If you do not specify this option, the user name specified by the -U option is assumed. o For subcommand list: -f n|s|v (Optional) Specifies the format of the output. See EXAMPLES for examples of each output type. o n - Displays the data in native format, as it appears in the crontab(1) database. SunOS 5.8 Last change: 5 Jan 2001 4 Maintenance Commands smcron(1M) o s - Default format. Displays the data in summary format. o v - Displays the data in verbose format. -h (Optional) Displays the command's usage state- ment. -o owner (Optional) Lists all jobs for the specified owner (user name). If you do not specify this option, all jobs in the crontab(1) database are listed. o For subcommand modify: -c command (Optional) Specifies the command that you want to run. -h (Optional) Displays the command's usage state- ment. -m day_of_month (Optional) Specifies the day of the month you want to run the job. Valid values are 1-31. If you specify both -t and -m options, the job exe- cutes one day per month at the time specified by -t. -M month (Optional) Specifies the month that you want to run the job. Valid values are 1-12.
